A basketball player uses a bat to hit a 0.145- kilogram stationary baseball with a force of 18,436 Newton's. What is the force, in Newton's, on the player's bat?
A. 2,673 newtons
B. 9,218 newtons
C. 18, 436 newtons
D. 36, 872 newtons
Answer: C
Explanation:
Newton's Third Law of motion states that any action causes an equal and opposite reaction. This is the fundamental requirement for the conservation of classical momentum.
The force, in Newton's, on the player's bat is 18, 436 newtons. The correct option is C.
What is force?The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.
Although modest, the gravitational force has a relatively wide field of effect. Maturity is always appealing. Since mass is its source, it operates between any two particles of matter in the universe.
Every action results in a corresponding and opposing response, according to Newton's Third Law of Motion. The basic prerequisite for the conservation of classical momentum is this.
Therefore, the correct option is C. 18, 436 newtons.

Think of an animal that has a distinctive or unusual body shapes. Describe how its body shape helps its momentum and how momentum affects its survival.
penguins! so momentum is based on mass and velocity, the advantages is that they have stored mass in the form of like fats to keep them warm however they are built to slide basically so that there is less friction when they travel so sideways their bullet like shape helps increase velocity so they have both mass and considerable velocity!

A ball weighted 20 Newton's rolls 20 meters in a straight line on a level surface. What is its change in potential energy?
A. 0 J
B. 1 J
C. 40 J
D. 400 J
[tex]\\ \rm\Rrightarrow Work\:done=Force(Distance)[/tex]
[tex]\\ \rm\Rrightarrow Work\:done=20(20)=400J[/tex]
Option D
The change in the potential energy of the ball is equal to 0J. Therefore, option (A) is correct.
What is the work?Work can be described as the energy used when a force is exerted to move an object through a specific displacement. The work done can be defined as it depends upon both the force on the object and the displacement by the object.
The displacement in a straight line in the direction of the applied force over a distance 'd'.
W= F × d
Where 'F' is the exerted force and 'd' is the displacement by the object.
The change in the potential energy or kinetic energy is equal to the work done.
The change in the potential energy = mgh₂ - mgh₁
The ball roll over the surface, h₂ = h₁
Therefore, the change in the potential energy is equal to zero.

If a scrapped car has a mass of 1,500 kg, what is the mass of the materials that can be recovered using a magnet?
The mass of the materials that can be recovered using a magnet is 1500 kg.
Law of conservation of matter
The law of conservation of matter states that matter can neither be created nor destroyed but can be converted from one form to another.
Based on this law of conservation of mass or matter, the mass of the scrapped car will remain constant and can neither change nor destroyed.
mass of scrapped car = mass of car recovered
Thus, the mass of the materials that can be recovered using a magnet is 1500 kg.

A convex, or converging, lens with a focal length of 34 cm is used to observe an image of an apple than is 80 cm away from the lens. At what distance from the lens does the image form and what type of image is it?.
The image distance is 59.2 cm and the image is real and small.
Image distanceThe distance of the image formed by the convex or converging lens is determined by applying the following lens equation.
1/f = 1/u + 1/v
where;
f is the focal length = 34 cmu is the object distance = 80 cmv is the image distance = ?1/v = 1/f - 1/u
1/v = 1/34 - 1/80
1/v = 0.0294 - 0.0125
1/v = 0.0169
v = 1/0.0169
v = 59.2 cm
Thus, the image distance is 59.2 cm and the image is real and small.

How long does it take an airplane, accelerating from rest at 5.00 m/s2, to travel 360 m?
19 yds is the same as how many meters
pleaseeee help me please t
Answer:
The current will remain unchanged:
If the switches are open then 18 Ω is in parallel with 18 Ω
This gives an equivalent resistance of 9 Ω for the circuit
R = R1 R2 / (R1 + R2) = (18 * 18)/ 36 = 9 Ω
Now suppose that switches are closed, then
each parallel combination of 6 Ω is in series with the other two
One combination = (6 * 6) / (6 + 6) = 3 Ω
There will be 3 of these parallel combinations in series providing a total resistance of 9 Ω which is the same as before so i is unchanged
A 23.3 kg crate is pushed with a force of 944 N for 36.0 seconds, moving the crate a distance of 12.4 m. How much power was used
Explanation:
[tex]p = \frac{f \times s}{t} [/tex]
power = Force × distance /time
power = 944N × 12.4m/36secs
power = (944×12.4/36)Nms—¹
power = 390.2Nms—¹ or 390.2Watts or 390.2Js—¹

You've got a flat tire. To lift your car, you make a homemade lever (see the figure (Figure 1)). A very light 1.6-m-long handle part is pushed down on the right side of the fulcrum and a 0.050-m-long part on the left side supports the back of the car.
How hard must you push down on the handle so that the lever exerts an 6900- N force to lift the back of the car?
How hard you must push down on the handle is by applying a force of 215.63 N
Moment of a forceThe moment of a force about a point is the turning effect of the force about that point.
The moment of a force M = Fd where
F = force and d = perpendicular distance of force from pivot point.Now, for you to lift up the car, the moment due to your force about the fulcrum, M equals the moment due to the force on back of car. M'
M = M'
FD = F'd where
F = Force applied, D = distance of force from fulcrum = 1.6 m, F' = force applied on back of car = 6900 N and d = distance of force on back of car from fulcrum = 0.050 mMaking F subject of the formula,we have
F = F'd/D
Substituting the values of the variables into the equation,we have
F = F'd/D
F = 6900 N × 0.050 m/1.6 m
F = 345 Nm/1.6 m
F = 215.625 N
F ≅ 215.63 N
So, how hard you must push down on the handle is by applying a force of 215.63 N

how density of arock can be determined using normal laboratory apparatus
Answer:
Explanation: Take the apparatus fill it with water which is enough to sink the rock, next write down the reading of the apparatus with only the water. next drop the rock in the water and write down the reading with the water and the rock. next calculate change in volume ( here volume is the reading in the apparatus). next find the weight of the rock.
Then put the values into this equation
Density = mass/volume
if you took all the units in SI units then the unit of density is Kg/m^3
The density of a rock can be determined using normal laboratory apparatus through a method known as the "Archimedes' principle" or the "water displacement method".
Materials needed: 1. Electronic balance or scale 2. Graduated cylinder or beaker 3. Water
1. Weigh the rock: Use an electronic balance or scale to measure the mass (weight) of the rock. Record this value in grams (g).
2. Find the rock's volume:
a. Fill the graduated cylinder or beaker with a known amount of water.
b. Note the initial water level reading in milliliters (ml).
c. Carefully lower the rock into the water, making sure not to splash or spill any water.
d. Measure the new water level in the graduated cylinder or beaker after the rock is submerged. Record the final water level reading in milliliters (ml).
e. The volume of the rock can be calculated by subtracting the initial water level from the final water level. This difference represents the volume of the rock displaced by water.
3. Calculate the density:
The density (ρ) of the rock can be determined using the formula:
ρ = Mass of the rock (in grams) / Volume of the rock (in milliliters)
4. Report the result:
The density of the rock is typically expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/ml).
This method can provide a reasonably accurate determination of the rock's density. However, keep in mind that the density may vary slightly depending on the specific rock composition and porosity. For precise measurements or for rocks with complex structures, more sophisticated laboratory techniques may be employed.

What happens to the speed of a sound wave as it passes from the air into the ground?
Answer:
SEE BELOW
Explanation:
Sound travels faster in warmer air, so the sound waves are refracted upward, away from the ground. Various atmospheric conditions can cause a temperature inversion, with air temperature increasing with height. This causes some of the sound energy from a source near the ground to be refracted back toward the ground.
